Translation of Stange's (1971) approach to tolerance limits in simple linear regression

In Stange (1971), Angewandte Statistik, Vol. II. Springer Verlag, Berlin, Heidelberg, New York, 141-143, the author derives a tolerance limit for simple linear regression which is widely used in ...

Extreme value function in R

I have a small data set (n=25) with an unknown distribution and I'm trying to find a distribution function that is as similar as possible in order to ultimately determine tolerance limits. I used the ...

Linear Model + tolerance intervals: How to show that when a condition is fulfilled for a tool it is also fulfilled for another related tool?

The problem Imagine that you have two different tools that produce data at given time points $t_1,...,t_m$. Suppose that we only have access to the mean and standard deviation of the data at each time ...

When to pool batches for tolerance intervals?

Imagine that we have at disposal several batches of data from a given process and that the interval time of record of each batches can be week, months or even years. Out of these data, we would like ...

Calculation of a nonparametric equal-tailed (central) tolerance interval for an unknown continuous distribution

Assume we have a sample of size $n$ from an unspecified continuous distribution $F(\cdot)$. We wish to construct a tolerance interval to contain $(100\,\beta)\%$ of the population with a pre-specified ...

Bootstrapping with quantiles of data instead of SD*z?

I have recently been bootstrapping the confidence intervals of a neural network model estimated to data. I execute the following psudo-code, which seems similar to previous bootstraps I have done: ...

Conditional Tolerance Interval

With the generous help of people here, I've recently learned about the notion of a Tolerance Interval (Confidence in a range estimate, and +- 2sigma rule of thumb). I am now working on an application ...

Prediction Intervals and Tolerance Intervals [duplicate]

I have a question regarding interpretation of prediction intervals and confidence intervals. The definitions I've seen is: (1) A prediction interval for a single future observation is an interval ...

How does the Empirical Rule align with Tolerance Interval

For Empirical Rule, 95% of the observed data will occur within the second standard deviation, but what is the difference between this and the 95/95 2-sided tolerance interval ? It includes 95% of ...

Lower confidence with larger sample size? Tolerance interval for distribution-free data

I am trying to find the sample size required in order to establish a tolerance interval which contain 99% of the population, with 95% confidence. The results from Minitab for a sample size of 473 are ...

Is it possible to estimate a specific quantile of a prediction based on the results of ordinary linear regression?

We can estimate mean value of a prediction with a specific confidence, we have an estimated value of a variance (MSE) and we also assume that prediction is a normally distributed random variable. Isn'...

interval depending on sample size

I came across these funnel plots here and tried to reproduce something similar where I have a normally distributed population and I happen to know the true population mean (500000) and standard ...

How to set the tolerance in Gradient descent?

I understand that one solution of setting the number of iterations, is to set it to a large number and then interrupt it when the gradient vector becomes tiny, so tiny that it is smaller than a ...
